IMPROVEMENT IN BRONZING-MACHINES.

Spooification forming part of Lottors Patont No. 219,094, datodSoptombor 2{1879; application filod Mny 17, 1879.

To all whom it may concern Bo ii: known that I, DAVID HESTON, of thocity and connty of Philadolphin, zmnd Stato of Pennsylvania, havoinvontod a now and usofnl Improvoxnont in Bronzing-Maobinos, whio bimprovomontis fully set forth in the following spooifioation and.aocompanying drawngs, in whioh- Figure 1 is a front olovation of thebronzng-maohino-ombodying 1ny invontion. Fig. 2 s n sido olovation,showing tho in torior thoro- 4 of. Fig. 3 is a horizontal soction of thobaso or bed plato and food-bars of tho fonntain.

Similar lottors of roforonco indicato corrosponding parts in tho sovoralfiguros.

My invontion consists of 2m improvod fonntain for supplying tho bronzono che shoots of papor to be bronzod.

It also consists of a throw-off for the bronzod shoet.

It; also consists of a whool having romovablo jogs for adjusting thoflOW and sproading of tho bronzo.

It also cons1sts of an adjnstablo baok-gndo on a. stnoionary tablo.

Roforring Lo tho drawings, A roprosonts a, oylindor, whioh is proporlymonntod upon tho sidos of the box B. 0 roprosonts two or moro gripors,whioh are 1ot into tho foce of tho oy1- indor A, so th-nt whon bhoy oroolosocl tho cylindor has an unbrokon surfaco. Tho numbor of tho griporsis in aooordanoo With the size of uho maohino, and thoy are thrown baokand olosocl by suitablo moans, tho ordinary appliancos, a, ornployod foroporating tho nippors of a printng-maohno boing adaptablo thorofor.

To the front of the box B is soonrod a stationa-ry foocLtablo, 1), onwhoh is fittod 2m adjnstablo foodgnido, b. In fooding tho shoobs to thomaohino thoy are plaood on t-ho tablo D, With tho baok end of ozwh shootrostod against tho guido b, instoad of against a front guido,

E roproson ts & hoppor or fon'ntain for tho bronzo, and to tho baso orbod plato F thoroof aro fittod two transvorso bars, G H, the bar orslido Gbaving rooiprooating motions impartod to it by mozms of a springsnitablyappliod, and cznns or jogs J, whioh oro rornovably connootod toa whool, K, whioh is soonrod to the drivingshaft. Tho bar H is adaptodno bo movod toward and from the slidoG, and il; is adjnstnbly hohl inposition by moans of scrows H H; tho sorows H passing loosoly tbroughone sido of the bod-plato and sorowing into t11o bar H, and the sorows Hongagngly fitt-od to the bod-plato, and having thoir ponfins in contao'uWith said bar. Atransvorso aperture ox ists in the bod-plato undornoaththo inner odgos of the slido and bar G H, andl tho sido of tho slido Gadjaoont to tho bar H is bovolod, so as to mako a wodgo-shapod throatbotwoon thom, tho widost pari: boing above.

Whon it is dosirod to incroaso or dooroaso -tho Wdth of said throat, thosorows H H are proporly turned, so as to acoornplish tho adjnstmonta andhold tho bar E in positimn By the movomont of the slido G tho bronzo iscansod to,drop through tho throat abovo statod to che shoot bolow, thoquantty boing rognlzmtod. by tho adjustrnont of t-ho throat. Tho flow ofbronzo ooasos ai: ntorvals whon tho sfido is not; in motion, and thonnmbor of jogs or cams J s to be inoreasod or docroasod,

so as to suit tho longth of tho shoot boing bronzod, whoroby tho flow ofbronzo is roadily oontrollod, and made to coaso ontiroly aftor tho shootboing bronzod has fully passod nndor tl1o fountain.

In the poriphory of tho oylndor A, botwoon tho gripors 0, is a, groovo,L, into wlrioh projocts and boars lightly tho point of a wiro, L, whosoothor end is soonrod 130 the tablo D or box B.

'lho gripors whoh hold tho sheot as it p-nssos throu g11 tho manchinoare made to open as the end of the shoot omorges from (ho maohine,

and the point of the wiro L, rosting in the groovo L, msos tho sheotfrom tho fono of the oylndor, and c'ansos ittopass out over tho rollor Mnpon a.n ordinary fly or a, tab1o placod to roooivo it. As the shootontors tho machino it passos nndor a rooiprocatin g pad or pnds, N, andcloaning-brushos P. v

Tho pad N sproads tho bronzo on tho shoot,

and its motion is dorvod in one diroobion from tho jogs or oanns J ontho whool K, and in tho othor dirootion by means of springs sntablyapplied.

As it is undosirablo for the pad or bare reeiproeating motions, exceptngwhen the sheet passes Lhereunder, the number of jogs or cams J requresto be increased or decreased in order to produce che relative motionsand stoppage of said pad or pads.

The operation of the slide G end shaft or arm fr0m whch che pad N ishuug is eased by means of rollers, which, eonnected to said sfide andslmft, are in eontaet Wh the jogs J.

In my Letters Patent No. 174,526, for improvement in bronzng-macbnes,granted 011 the 7th day of March, 1876, provison is made for thevertical adjust ment of the seraper above the bottom of the feedtroughbut. there is no adjustment 'of the feed-slide by mezms of two sets ofscrews operating as in the present invention. Said patent hes neitherthe throwfi' wire and grooved cylinder, the removable and zuljusnablejogs or cams, nor che stationary table of the present case, wherefore Ihave shown new and valuable featnres end made un improvement in the art.

Hevin thus described my invention, whatl claim es new, and desire toseeure by Letters Patent, is-

1. In a bronzing-machine. che transverselyoperated feed-slide G endadjust-able bar H, in eombination with the serews H and H, the screws Hfibted to the bed plate end beari11g against the bar H, and the serews Hpassing loosely through the bed-plate and serewng into sad bar,substantially as and for the purpose set forth.

2. The eylinder With groove L, in combination With the throw-off' wireL, substantally as and for che purpose set forbh.

3. The eombination, With the feed-slide aud pzul N, one or both, of thewheel K, provided With removable an(1 adjusoable jogs or eams J,substanbially as aud for the purpose set forth.

4. In a bronzing-maehue, che cy1inder A, Wth gripers C, in combinationWith the stationary table D, provided with an adjustable baek-guide, b,substantially as and for che purpose set fortah.
